Defect Properties of Na and K in Cu2ZnSnS4 from Hybrid Functional Calculation

, 2017
In-growth or post-deposition treatment of $Cu_{2}ZnSnS_{4}$ (CZTS) absorber layer had led to improved photovoltaic efficiency, however, the underlying physical mechanism of such improvements are less studied. In this study, the thermodynamics of Na and K

Efficient Kesterite Solar Cells via Scalable Doctor‐Blading of 2‐Methoxyethanol‐Based Molecular Ink

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A new record efficiency of 13.26% has been achieved for doctor‐bladed CZTSSe solar cells, fabricated for the first time from an MOE‐based molecular ink in ambient air. Cu2ZnSn(S,Se)4 (CZTSSe) thin‐film solar cells have garnered significant interest owing to their appealing properties, such as earth‐abundant composition, environmental friendliness, high

Analysis of CZTSSe Monograin Layer Solar Cells

, 2011
Monograin layer (MGL) solar cell combines the features of a monocrystalline solar cell and a thin film solar cell. The photoactive layer is formed from the kesterite-stannite semiconductor Cu2SnZn(S,Se)4 (CZTSSe) material with the single-crystalline grains embedded into the epoxy resin (Altosaar et al., 2003).
